To all whom it may concern:

Be it known that 1, CHARLES G. ROSEN- BERGER, citizen of the United States, residing one of the uprights of the apparatus.

at Savannah, in the county of Wayne and State of New York, have invented certain new and useful Improvements in Gymnastic Apparatus, of which the following is a specification.

This invention relates to gymnastic apparatus and more particularly to a novel supporting frame for horizontal bars and trapeze.

It is the primary aim of the present invention to provide an apparatus of this class which may be readily set-up in any ordinary room of suitable size without in any way marring the floor or walls of the room and which, when'set-up will be substantial and not liable to vibration while in use.

Another aim of the invention is to so construct the apparatus that it may be arranged to support horizontal bars and trapeze of various widths and at practically any desired elevation.

Another object of the invention is to provide a gymnastic apparatus of the class mentioned which may be manufactured at a low cost and readily set-up by any one without the use of tools with the possible exception of an ordinary wrench.

For afull understanding of the invention reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective View of the apparatus embodying the present invention.

Fig. 2 is a vertical sectional view throbugh 1g. 3 is a horizontal sectional view through a pair of uprights and illustrating a top plan. Fig. 4: is a detail perspective view of one of the sections of one of the uprights. Fig. 5 is a view similar to Fig. 2 illustrating another arrangement of the sections of one of the standards.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

In the drawing, and particularly in Fig. 1, there is illustrated one arrangement of the apparatus embodying the present invention, and it will be understood that any number of frame devices may be employed and that they may be arranged in different ways, the showing of this figure being merely intended to show one arrangement.

As stated above, one or any number of frame devices constructed in accordance with this invention may be employed and each of said devices includes essentially a pair of spaced uprights of counterpart construction.v Each of these uprights includes a base consisting of a metallic head 1 provided axially with an upstanding threaded stud 2. This head 1 is formed in its under side with a number of threaded sockets 3 and disposed against the under side of the head 1 is a circular block 4 of rubber or other suitable compressible material. Screws 5 are inserted through openings6 in the block 1 and have their heads received in countersinks 7 formed in the under side of the block and these screws are threaded in the sockets 3in the head which will serve to secure the block in place against the under side'of the head. The lower section of each upright is indicated by the numeral 8 and is in the nature of a post which is circular or rec tangular or of some other form in cross section and this post is formed at its lower end with a threaded socket 9 into which the stud 2 is to be screwed when the parts are being assembled. At its upper end the post 8 is formed with a threaded stud 10 and this stud is designed to fit in a threaded socket '11 in the lower end of another post section 12.

In addition to the head or base above described, each upright includes a ceiling engaging head of the same construction as the first described base or head and includes a head section 13 corresponding to the head 1 and a block 1 1 of compressible material corresponding to the block 1, the portion 14:

- being secured to the upper flat side of the head section 13 by means of screws 15 arranged in the same manner as the screws 5. The head section 13 is formed axially upon its under side with a downwardly projecting threaded stud 16 which is designed to be threaded into a socket 17 formed in the upper end. of a post-section 18 which is of the same construction as the section 8, previously described, and in fact these sections are interchangeable. If desired,another or several more of the sections 12 may be employed in connection with the post section 18 and the one indicated at 8 and in addition to these several sections and the two heads,

each upright includes an intermediate post section which is adjustable as to length and which will now be described.

The adjustable section above referred to includes a member 19 which is tubular throughout a portion of its length and in tcriorly threaded as at 20 and which at its lower end formed with a threaded socket 21 arranged to receive the stud 10 or a simi lar stud an formed at the upper end of the post section 12. This adjustable section also includes a member 23 which is tubular throughout a portion of its length and interiorly threaded as at and is provided at its upper end with a threaded stud 25. A section 26 is provided and is formed at each end with a threaded socket 27 and one of these sections may be threaded upon a stud 28 at the lower end of the section 18 and at its other end may receive the threaded stud In addition to the members 19 and the adjustable post section includes a threaded member 29 which is formed between its ends with a head 30 which may be square, hexagonal or of any other suitable form and the said member 29 between its ends and the said portion 30 is reversely threaded as at 31 and 32. The end 31 is adjustably threaded into the upper threaded end of the member 19 and in like manner the portion 32 of the adjusting member is threaded into the lower end 24c of the member 23. [it this point it will be understood that after the sections of the post or up right have been assembled and a sufficient number thereof have been employed to produce an upright of a length substantially equal to the height 01 the room in which the apparatus is to be arranged, the same may be disposed in upright position and the member 29 may then be rotated so as to further lengthen the upright as a whole and bring the block 14 of its head 13 in position bearing firmly against the ceiling of the room. The upright will in this manner be firmly supported in position, although the finish of the floor and the paper upon the ceiling will. not be injured. In order to hold the parts at adjustment, a Washer 33 is fitted upon the portion 32 of the member 29 and a nut 34- is also fitted upon this said portion of the member below the washer and is adjusted upon the member so as to cause the washer to bear firmly against the lower end of the member 23. In a like manner a washer 35 is fitted upon the por tion 31 or the member 29 and a nut 36 fitted upon this said portion is arranged to be tightened or threaded down upon the portion so as to cause the washer to bear firmly against the upper end of the member 19.

The means provided for supporting the horizontal bar of the apparatus is identical with that employed in supporting the suspension bar of the trapeze and the horizon-- tal bar is indicated in the drawing by the numeral 36 and the trapeze suspension bar by the numeral 37. Each of these bars is provided at each end with a ferrule 28 having its outer face concaved at as 39 and fitted with a split ring =l-0 which is of the shape to fit the uprights at any point in their length. This ring 40 is lined as at s1 with rubber or other suitable material and a clamping screw 4:2 is engaged through the outturned ends of the ring 40 and may be tightened for the purpose of clamping the ring about the respective uprights, it being understood that the rubber ring all will effectually hold the split ring against sliding down upon the uprights. The trapeze suspension ropes are indicated at 13 and at their lower ends may support a trapeze bar 44 or the ordinary flying rings.

If desired, a net may be employed in conneotion with the apparatus and may be sub-- stantially of the construction shown in Fig. 1, and consisting of a frame 45 made up of a number of lengths of rod or tubing detachably fitted together by screw joints and having stretched over its top a sheet of netting or cloth 46.

By reference to Fig. 3 of the drawings it will be observed that each of the sleeves 38 is open from end to end and that the ends of the bar 36 are concave so as to fit against and partly embrace the posts by reason of which construction the bar is held against turning movement in the sleeves.

Having thus described the invention What is claimed as new is 1. In an apparatus of the class described, spaced uprights, smooth and cylindrical, bearing heads at the upper and lower ends of the uprights, means for adjusting the uprights as to length, and a rigid bar eX- tending between the uprights and connected at its ends thereto and verticaly adjustable thereon, the said bar constituting the sole connection between the uprights.
